KENNETH W. DAUGHDRILL, OF AUSTIN, TEXAS.

ELECTRC SIGN.

Application filed February 11, 1919.

i o l e muil, a citizen of the United States, residing at Austin. in thecounty ot Travis and State ot Texas/have invented new and uselfullmproements in Electric Signs, ot Which the following` is aspecification.

This invention relates to the method of making and the novelconstruction ot illuminating signs ot that class in which a plate havingtransparent letters or characters thereon is placed bei'ore a lightingmedium so that the rays oit light will pass through the transparentportions.

The principal obj ect ofthe invention 1s to provide small protuberanceson the plate which outlined lthe letters or characters and which aretranslucent so that the sign can be read at night, when illuminated, orduring` the day.

The invention also consists in certain other features ot constructionand in the combination and arrangement ot the several parts, to behereina't'ter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

ln describing my invention in detail. ret erence will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a iront view ot a sign conn structed in accordance With thisinvention.

2 is a view of the rear tace of the fio/tom t may conce/Mz it known thatl, KENNETH W. DAUGH- an enlarged section on line 3-3 s a rear view otthe sign box.

l`|` iI a section on line h of Fig. 4. .l1 these views, l indicates atrame constructed similar to a picture traine. 2 indi- Cates the signplate. having` the sign printed on its trent tace in any suitablemanner. his plate fits in the trarne, as shown. 3 indicates the bei;which is of pyramid form and has its base iitting in the frame andabuttingy the sign plate. he parts are held #together by the upper andlower latches 4 so thatv said parts may be separated when desired. lpre'ter to make the box from a single strip ot material, which is bentinto suitable form and has its meeting edges suitably screwed together.The inner surface ot' the box is painted with a coating oi any suitablereflecting material. r-in electric light socket 5 is secured to one ofthe inner faces Specification of Letters atent.

oit the boi; to receive an electric lamp `6, theV wires 'from Which maylead to any suitable source oi2 current. It' desired this socket may beprovided With the 1Well known type of tlasher attachment so asto makethe light intermittent. Y

The sign plate is first printed with the sign which it is to cont-ainand this plate may be made of metal, cardboard or any other suitablematerial. The letters or characters which are to beilluminated are thenoutlined by a series of holes punched through the plate, as at 7. Astrip 8 of cloth, paper or other suitable material that Will stretch andis translucent, is pasted to the back of the plate, over said holes.Portions ot the strip, While still Wet, are then pushed through theholes to torni protuberances 9. These protuberances project Jfrom theprinted face ot the plate so that the letters can be easily seen duringthe day and at night, when the box is illuminated, the saidprotuberances will give the'etfect ot a plurality ot small electriclight bulbs outlining the letters. When the adhesive With which thestrip is coated becomes dry the protuber'- ances will retain their shapeeven though the plate is subjected to rough handling.

I find it desirable to outline the letters composingthe Words of thesign that are not to be given the prominence 0f the main Word or Wordsby small holes l0 and pasting strips ll on the back of the sign plateover said' small holes but this strip is not to be punched through theholes. Y

It will thus be seen that an attractive and effective sign is producedwhich can be manufactured to sell at low cost. While the sign is mainlydesigned for indoor use it may be used out of doors by treating the faceof the sign and the protuberances With a Waterproofing composition orcovering the face of the sign with glass.

Having thus described my invention, what l claim is rlhe hereindescribed method of forming a sign plate consisting in first outliningthe sign characters on the plate by aseries of holes, pasting a strip ottranslucent material having an adhesive coating on one tace thereof onthe rear oi said plate over said holes and finally forcing the materialthrough said holes to form hollow protuberances on the front face ot theplate.

2. The herein described method of forming a sign plate consisting infirst outlining Y the sign characters on the plate by a series of holes,pasting` a strip of translucent and flexible material onthe rear of saidplate over said hole after treating said strip with a stilening andadhesive solution and linally forcing the material While still Wetthrough the holes to form hollow protuberances on the front face of theplate.

3. A sign plate having the characters thereon outlined by a series oftranslucent hollow protuberanees formed from flexible material treatedwith a stilfening solution and means 'for illuminating saidprotuberanoes.
